My iPad is stuck on headphones only
how do I get my iPad to get sound in the speakers its play only with head phones
iPad Air, iOS 9.3.1
Try a simple reset first
After shutting down all open apps using the app switcher - invoked by quick double press of the home button and swiping up on each app till it flies off the screen.
Hold the sleep/wake and home buttons down together till you see logo - then release and allow normal boot up
IF that does not work - then plugging the headphone in and out will dislodge the locked mode
